This is a diode low pass filter with patch points within the resonance path. This allows you to patch the resonance audio path through a filter or VCA to create interesting and complex resonances.
Compatible with 12V or 15V systems. The Pots are PCB mounted, but all other parts are mounted off board.
Audio Demo: With VCA in resonance loop
Audio Demo: With Low Pass VCF in resonance loop
Audio Demo: With High Pass VCF in resonance loop
For complete descriptions of the way the module is used, mp3 samples and how to build it, including schematics and parts list; download this PDF file.
Boards are available now. Price for a PCB is $8.
Unfinished eurorack
panels are available for this project, they are 6HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
